I did the math on the plate voltage on the 6J5 and it would appear that it's not drawing much current at all like 5 microamps, should be abt 5ma. From the chassis the the - side of the filter caps should have abt -15vdc. If is 0 then that would add to the high volt 15v. If you remove the cap on the 6B6 and touch the grid cap does it buzz really loud??
The number next to the cathode pin that doesn't have a "v" is indicating the cathode current not the voltage as most a tied to chassis ground so there would be no voltage there.
To get a better idea what the pri of the power trans whats to see measure the heater voltage (6.3vac) and set your variac accordingly.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
